Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, specifically to an auxiliary mechanical device for disassembling and assembling experimental glassware. Background Technology

[0002] In the research and development and production activities of chemical and synthetic biology laboratories, various glass instruments are often used. During the use of these instruments, glass components such as condensers, evaporators, and collection bottles need to be disassembled and replaced at any time.

[0003] During the disassembly and assembly of glassware, some instruments are quite tall, even exceeding the height of the operators, and are also heavy. Typically, two to three operators are needed to work together to ensure safe disassembly and assembly. Furthermore, glassware is inherently fragile and easily damaged. During manual handling and assembly, even slight carelessness can lead to impacts and damage, resulting not only in economic losses but also potential safety hazards from glass shards, threatening the personal safety of the operators. Utility Model Content

[0004] This invention provides an auxiliary mechanical device for disassembling and assembling laboratory glassware, which facilitates the disassembly and assembly of glassware, reduces the waste of human resources, and lowers the risk of glassware being damaged by impact.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: An auxiliary mechanical device for disassembling and assembling experimental glassware includes a horizontal guide rail, a first rocker arm, a second rocker arm, and a glassware clamp. A slider is slidably connected to the horizontal guide rail. The bottom of the slider is rotatably connected to the upper end of the first rocker arm via a first rotating joint. The lower end of the first rocker arm is rotatably connected to the upper end of the second rocker arm via a second rotating joint. The second rocker arm includes an upper rocker arm, a lower rocker arm, and a spring. The upper end of the upper rocker arm is bolted to the second rotating joint, and the lower end is bolted to the glassware clamp. The upper end of the lower rocker arm is bolted to the second rotating joint, and the lower end is bolted to the glassware clamp. The upper end of the spring is hinged to the upper rocker arm, and the lower end is hinged to the lower rocker arm.

[0006] Furthermore, the upper rocker arm is parallel to the lower rocker arm, and the lines connecting the upper hinge point of the upper rocker arm to the upper hinge point of the lower rocker arm, and the lines connecting the lower hinge point of the upper rocker arm to the lower hinge point of the lower rocker arm, are always kept vertical.

[0007] Furthermore, the upper end of the spring is close to the second rotating joint, and the lower end is close to the glass clamp.

[0008] Furthermore, the upper end of the first rotating joint is connected to the slider via a damped shaft, and the lower end is fixedly connected to the upper end of the first rocker arm; the upper end of the second rotating joint is connected to the first rocker arm via a damped shaft.

[0009] Furthermore, the glassware clamp includes a support column, clamps, and a connecting seat. Multiple clamps are connected to one side of the support column along its length, and a connecting seat is fixed to the other side of the support column. The connecting seat is hinged to the upper rocker arm and the lower rocker arm, respectively.

[0010] Furthermore, there are three clamps, each with a diameter adapted to the outer diameter of the glass container wall at the clamping point.

[0011] Furthermore, the slider includes a first slider and a second slider. The cross-section of the first slider and the horizontal guide rail are both U-shaped and open in the same direction. The second slider includes a cover and a mounting block connected to the center of the cover. The first slider is sleeved on the outside of the horizontal guide rail, and its two ends of the opening are fixedly connected to the two ends of the cover of the second slider. The mounting block slides in cooperation with the inner wall of the horizontal guide rail.

[0012] Furthermore, a rolling element is provided between the mounting block and the horizontal guide rail.

[0013] Furthermore, the rolling element is a ball, and a limiting groove is provided on the surface of the mounting block that contacts the ball, so that the ball rolls within the limiting groove.

[0014] Furthermore, the horizontal guide rail has a continuous limiting groove along its length on the surface in contact with the ball, and the ball rolls within the continuous limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention enables the overall horizontal movement of the device through a combination of a horizontal guide rail and a slider. The two-section rocker arm allows the held glass to move vertically or rotate 360° within its arm length, while maintaining a vertical position. The elastic force generated by the spring structure within the rocker arm, combined with the frictional force generated by the bolt tightening, resists the weight of the glass and its clamps, as well as the torque generated by gravity, ensuring stable suspension of the glass at any lifting height. This invention allows for arbitrary movement of the glass, facilitating assembly and disassembly, reducing wasted manpower, and lowering the risk of damage from impacts. Attached Figure Description

Therefore, it should not be construed as a limitation of this application.

[0020] In the description of the embodiments of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1 , Figure 2 As shown, an auxiliary mechanical device for disassembling and assembling experimental glassware includes a horizontal guide rail 1, a first rocker arm 2, a second rocker arm 3, and a glassware clamp 7.

[0022] A slider 4 is slidably connected to a horizontal guide rail 1. The slider 4 includes a first slider 41 and a second slider. Both the first slider 41 and the horizontal guide rail 1 have U-shaped cross-sections and open in the same direction. The second slider includes a cover 42 and a mounting block 43 connected to the center of the cover 42. The first slider 41 is sleeved on the outside of the horizontal guide rail 1, and its two ends are fixedly connected to the two ends of the cover 42 of the second slider. The mounting block 43 slides against the inner wall of the horizontal guide rail 1. In some embodiments, a rolling element 44 is provided between the mounting block 43 and the horizontal guide rail 1 to reduce the friction of the slider 4 when it moves along the horizontal guide rail 1, thus making it easier to push the device horizontally. Preferably, the rolling element 44 is a ball bearing, and a limiting groove is provided on the surface of the mounting block 43 that contacts the ball bearing, allowing the ball bearing to roll within the limiting groove. Further, a continuous limiting groove is provided along the length direction on the surface of the horizontal guide rail 1 that contacts the ball bearing, allowing the ball bearing to roll within the continuous limiting groove. It is understandable that the ball bearing 44 is in rolling contact with the horizontal guide rail 1 and the mounting block 43, and there is no specific limit to the number of balls on each contact surface.

[0023] The bottom of slider 4 is rotatably connected to the upper end of the first rocker arm 2 via the first rotating joint 5. The upper end of the first rotating joint 5 is connected to slider 4 via a damped shaft, and the lower end is fixedly connected to the upper end of the first rocker arm 2. The lower end of the first rocker arm 2 is rotatably connected to the upper end of the second rocker arm 3 via the second rotating joint 6. The upper end of the second rotating joint 6 is connected to the first rocker arm 2 via a damped shaft. The second rocker arm 3 includes an upper rocker arm 31, a lower rocker arm 32, and a spring 33. The upper end of the upper rocker arm 31 is bolted to the second rotating joint 6, and the lower end is bolted to the glass clamp 7. The upper end of the lower rocker arm 32 is bolted to the second rotating joint 6, and the lower end is bolted to the glass clamp 7. The upper end of the spring 33 is hinged to the upper rocker arm 31, near the second rotating joint 6, and the lower end of the spring is hinged to the lower rocker arm 32, near the glass clamp 7.

[0024] The upper rocker arm 31 and the lower rocker arm 32 are parallel. The lines connecting the upper hinge point of the upper rocker arm 31 to the upper hinge point of the lower rocker arm 32, and the lines connecting the lower hinge point of the upper rocker arm 31 to the lower hinge point of the lower rocker arm 32, remain perpendicular, forming a parallelogram-shaped linkage structure. This ensures that the glass container 8 remains vertical during movement, preventing spillage or misalignment due to tilting during lifting. The elastic force of the spring 33, combined with the friction generated by the bolt tightening, resists the weight of the glass container 8 and its clamps, as well as the torque generated by gravity, ensuring stable suspension of the glass container 8 at any lifting height. Those skilled in the art can calculate the required spring force for suspension based on force analysis (the analysis and calculation process is common knowledge and will not be elaborated upon here), and reserve a certain safety margin, thereby selecting a spring with a suitable model and parameters from the existing technology.

[0025] The glass clamp 7 includes a support column 71, clamps 72, and a connecting seat 73. Multiple clamps 72 are connected to one side of the support column 71 along its length, and the connecting seat 73 is fixedly connected to the other side of the support column 71. The connecting seat 73 is hinged to the upper rocker arm 31 and the lower rocker arm 32, respectively. In this embodiment, there are three clamps 72, each with a diameter adapted to the outer diameter of the glass 8 wall at its clamping location.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
